' SMOKING APPIJANCE Galen M. Pierson, El Paso, Tex. Applicationflctober 2'7, 1938, Serial No. 237,315 5 Claims. (01. 131 -209} This invention relates to an improved smoking appliance constructed to provide means for cooling and cleaning the smoke passing therethrough,

It is an, aim of this invention to provide an improved attachment for use with cigar and cigarette holders or pipes which will form a trap to catch the nicotine carried by the smoke and which will direct the smoke by an indirect route to permit-it tobe cooled before reaching the mouth of the smoker.

More particularly, it is an aim of this invention to provide an improved construction of stem for pipes or cigar and cigarette holders provided with a chamber adapted to contain a removable insert, which diverts the smoke passing therethrough by a plurality of indirect channels for cooling the smoke and for entrappingthe nicotine; said insert being readily removable and so constructed that it. may be easily cleaned.

Still a further aim of theinvention, is to provide a stem for smoking appliances in which an improved trap may be removably mounted, said trap being constructed to connect the opposite ends of the stem to thereby form a chamber 'in which it is removably contained.

Other objects and advantages of the invention will hereinafter become more fully apparent from thefollowing description of the drawing, which illustrates a preferred embodiment thereof, and wherein: 1 I Figure 1 is a side elevational view showing the invention embodied in a smoking pipe,

Figure 2 is an enlarged side elevational view partly in section, of the same embodiment, showing the means for removably mounting the insert,

.Figure 3 is a plan view of one side or face of the insert, v

Figure 4; is a sectional view taken along the line 4-4 of Figure 3,

Figure 5 is a plan view of the inner side of the removable socket member, and a Figure 6 is a sectional view taken along the line 6-8 of Figure 5.

Referring more particularly to the drawing, wherein like reference characters designate like or corresponding parts throughout the different views, ill designates generally a smoking pipe, which has been illustrated in Figures 1 and 2, constructed in accordance with the present invention. I-Iowever,it is to be understood that the invention, which will hereinafter be described, may be equally well adapted to cigar and cigarette holders, as will hereinafter be explained.

Pipe 10 is provided with a bowl ll, of conventional construction, having an internally threaded outwardly projecting socket portion l2 formed integral with a portion of the lower part thereof and provided with a passage l3 extending through the lower part of the bowl I I and centrally through the socket portion l2.

A stem l4 having a longitudinal passage I5 is provided with a bit l6, at one end, of any suitable construction, and is internally threaded at its opposite end to receive the externally threaded tit ll of the socket member l8 which is provided with the internally threaded portion I9 corresponding with portion of socket l2. It will thus be seen that the socket member I8 is removably mounted in the stem M by means of its threaded tit l1, and as seen inFigure 2, is provided with a bore 2| which extends centrally through the socket member l8 and the tit I! to communicate with bore l5.

A disk-shaped insert, designated generally 22, is provided with a threaded periphery 23 adapted to engage the internally threadedfianges l9 and 20 of the socket members l8 and [2, respectively, as seen in Figure 2, to connect these parts to thereby form the chamber 24 in which the insert 22 is adapted to be removably mounted. As seen in Figure 2, the periphery of the rocket members I2 and I8 are of the same size and the flanges I9 and 20 are the same thickness and length so that when assembled on the insert 22 the two socket members fit flush against each other to provide a smooth outer surface. Furthermore, the thickness of the chamber 24 formed by the socket members is substantially equal to the thickness of the insert 22 so'that its opposite sides rest flush against the inner sides of the socket members l2 and l8.

One side of the insert 22 is provided with a recess 25 which communicates with the transverse passages'26 which are disposed in opposed relationship to each other and adjacent the periphery 23, as seen in Figures 3 and 4. The opposite side of the insert 22 is provided with the spiral grooves 2! and 28. The corresponding ends of each of these grooves connectwith the concave centrally disposed recess29 in the center of this last mentioned side, while the opposite ends of the grooves 21 and 28 each connect with an end 0 fa passage 26 to combine with the recess 25 for forming two continuous conduits from the center of one side of theinsert 22 to the center of the opposite side.

As seen in Figure 2, insert 22 ismounted in chamber 24 with the recess 25 facing toward the socket l2 and communicating with the passage I3, while the opposite side of the insert lies flush against the inner side of socket l8 which thereby converts the grooves 21 and 28 into spiral passages extending from passages 26 to the recess 29, which communicates with passage 2i.

From the foregoing it will be seen, that smoke may pass from the bowl H through passage 13 to the recess 25 where it may divide and pass in opposite directions, radially outwardly, to the two transverse passages 25 which convey the smoke to the opposite side of the insert 22 from whence it passes through the grooves or passages 21 and 28 to recess 29, thence through passage 2! through passage 15 and through the bit Hi. It will thus be seen, that the insert 22 forms a trap which collects the nicotine from the smoke passing-merethrough and which carries the smoke by an indirect route giving it an opportunity to be cooled before entering passage l5. Obviously, insert 22, which is readily removable, can be easily cleaned, since when removed the recess 25 and the grooves 21 and 28 are exposed and may easily be wiped clean of any nicotine collected therein and the passages 26 which are very short can likewise be easily cleaned before replacing the insert.

Although the invention has been illustrated in connection with a smoking pipe it is obviously equally well adapted for cigar and cigarette holders in which form, the socket 12, instead of being formed integral with the pipe bowl could, be formed integral with the cigar or cigarette receiving end of a holder or could be removably connected thereto as the socket I8 is connected to the stem M. The size of the sockets I2 and I8 and the insert 22 could each be correspondingly decreased when the invention is constructed in the form of a cigar or cigarette holder, and may likewise be decreased in size when constructed as a pipe, if desired, as the invention is not intended to be limited by the drawing and description to any particular size or proportions of the various parts thereof.

Various other modifications and changes are likewise contemplated and may obviously be resorted to without departing from the spirit of the invention, and the right is expressly reserved to make such variations and changes as fall within the spirit of the invention as hereinafter defined by the appended claims.
